混淆包含SlidingMenu、gson等Android代码的proguard写法

在混淆包含SlidingMenu的代码时，可能会报以下错误：

can't find superclass or interface com.google.android.maps.MapActivity

...

如果还使用到了gson来序列化或者反序列化json，程序还会抛出NullPointerException，这是因为代码被混淆后，成员变量以及getter、setter的名字都变了，这样就不能正常的序列化。

jni同理。

以下是本人使用的proguard.cfg，遇到此类错误的可以参考一下：
